2. Related Art

A rear view device typically includes a base assembly to be attached toa vehicle and a head assembly to be moveable relative to the baseassembly. Generally the head assembly of a rear view device can berotated between a driving position and a parking position.

The term “rear view” may refer to a view of the surrounding area, whichis not in the field of view of a driver of a vehicle, i.e. thedirections opposing, left, right, below and above of the viewingdirection, but can also comprise the view in the direction of theviewing direction of the driver and/or any combinations of thedirections. The rear view can be achieved via at least one rear viewelement in form of a reflective element like a mirror and/or an imageacquisition means like a camera. The rear view, that is the field ofview of the driver, can be adjusted by moving, in particular rotating,the reflective element and/or the image acquisition means. This in turncan be realized by moving the complete head assembly together with thereflective element and/or the image acquisition means such that the headassembly of the rear view device can be rotated also between a pluralityof viewing position.

For moving the head assembly, the reflective element and/or the imageacquisition means an actuator assembly is comprised by the rear viewdevice, which can be controlled by a first control unit within thevehicle. Also the image acquisition means can be controlled via a secondcontrol unit, wherein both control units may be formed together.However, for the purpose of controlling data have to be transferredbetween the rear view device and the control unit within the vehiclerequiring a harness.

For facilitating moving the head assembly together with the reflectiveelement and/or the image acquisition means specific pivot joint systemshave been developed, see WO 2018/215599 A1, as well as specific actuatorassemblies, see WO 2019/002627 A1.

DETAILED DESCRIPTION

FIGS. 1a to 2d show a retainer means 301 of a retainer assembly 300 tobe arranged between a base frame 110 of a base assembly 100 of anexterior rear view device 1 and a door panel 605 of a door 600 of avehicle 2. The retainer means 301 may be manufactured from a plasticmaterial, whereas the base frame 110 is metallic and may be manufacturedfrom aluminum.

The FIGS. 1a to 1c also show a harness 400 for electrically connectingin particular a power source and a control unit within the vehicle (notshown) with electric components of the exterior rear view device. Suchelectric components may comprise, as e.g. shown in FIGS. 3a to 3g , anactuator assembly 210 suitable for moving a head assembly 200 togetherwith a reflective element (not shown) relative to the base frame 110supporting the head assembly 200, and a camera 700 as well as anindicator means like a turn signal indicator 710 shown in FIG. 7. Saidharness 400 may comprise a camera harness 410.

The retainer means 301 is a multi-function component. The differentfunctions will be described with respect to the other components of theexterior rear view device 1 as well as the vehicle 2 in the following.

A function of the retainer means 301 is harness sealing, managingharness routing and accommodating variation in the camera harness 410and cleaning systems (not shown), as described in the following:

-   -   The base frame 110 has a door attachment portion 115 at one end,        with said door attachment portion 115 being provided with an        opening 124 for a harness holder 500 at its lower, free end, as        best seen in FIGS. 1d and 1e . Said harness holder 500 is formed        with a fixing tie 510 for holding the harness 400 and a clip 520        for connecting the holder 500 to said door attachment portion        115 by passing through the opening 124.    -   The base frame harness locator opening feature governs harness        position length the door side and the rear view device side, and        provides a strong retention eliminating risk of the harness 400        being misplaced e.g. by being pulled through during handling.        Further, the locating feature leads to reduced tolerance of        fit-to-door. In other words, the harness 400 is firmly located        to the base frame 110 in all directions allowing a solid datum        strategy for harness lengths and provides the ability to hold as        well as transport the exterior rear view device 1 whilst holding        on to the harness 400.    -   The harness 400 as well as the camera harness 410 divided        therefrom above the harness holder 500 extend between the door        attachment portion 115 of the base frame 110 and a holding        portion 320 of the retainer means 301 to an upper end of the        door attachment portion 115, which turns into a main portion of        the base frame 110 extending away from the door panel 605        towards the head assembly 200, being provided in form of an arm        116, with a head assembly attachment portion 117 of the base        frame 110 being provided at the second end of the base frame 110        opposite the first end, see e.g. FIG. 3 a.    -   The retainer means 301 is provided with a guiding projection 122        for guiding the camera harness 410 to a sealing portion 310 of        the retainer means 301 extending substantially perpendicularly        to the holding portion 320 to cover the camera harness 410 at        its bending region at the transition between the door attachment        portion 115 and the arm 116.    -   While the base frame 110 is provided with a harness guiding        channel portion 140 for guiding the harness 400 and a camera        harness guiding channel portion 123 for guiding the camera        harness 410, the holding portion 320 of the retainer means 301        also provides a camera harness guiding channel portion 340 to        substantially close a channel 420 for the camera harness 410, as        shown in FIG. 1 c.

As the retainer means 301 is not metallic, the sealing of the harness400, together with the camera harness 410, as well as the attachment ofthe metallic base frame 110 to the door panel 605 becomes safer. Thedesign of the retainer means 301 allows to accommodate different sets ofharness and cleaning system for all variations of mirror trim level.Further, the retainer means 301 ensures an easy assembly to seal inparticular the camera harness 410 after being mounted and to manage itsrouting along the base frame door attachment portion 115, withoutdeparting from the commonly used datum system between the base frame 110and the door panel 605, further illustrated in the following:

-   -   The base frame 110 is provided with a location pin 120 as well        as a T shaped location projection 121 belonging to the datum        system ensuring a correct assembly of the components of the        exterior rear view device 1 and a correct attachment of the        exterior rear view device 1 to the vehicle 2. The location pin        120 and the T shaped location projection 121 extend        substantially perpendicularly to the plane of the door panel        605, as can be best seen in FIGS. 2a and 2d . The retainer means        301 is provided with an opening 322 for the location pin 120 and        a hook 350 with openings 351 for the arms of T shaped location        projection 121, as can be best seen in FIG. 2b . FIG. 2d        illustrates that the location pin 120 as well as the T shaped        location projection 121 pass through the respective openings        322, 351 of the retainer means 301 to also pass respective        openings 610, 620 within the door panel 605 to engage the same,        with the hook 350 of the retainer means 301 ensuring the        respective engagement.    -   The base frame T shaped location projection 121 and the location        pin 120 provide the primary and secondary datum strategy to the        door datum system in X+Z directions, while the Y direction is        controlled using three screw bosses. The door panel 605 in FIG.        2d shows two screw openings 631 and 632 aligned to two screw        openings 131 and 132 of the base frame 110, respectively, which        in turn pass openings 371 and 372 of the retainer means 301.    -   Thus, the corresponding locating features of the base frame 110        and the retainer means 301 allow base frame datum features to        interface with the door 600 minimizing tolerance of datum        strategy.    -   Further location projections 125, 126 and 127 are provided by        the door attachment portion 115.

The retainer means 301 along with the location pin 120 and the T shapedlocation projection 121 not only provides an accurate assembly to thedoor panel datum system, but also facilitates the assembly as itprovides a robust 3rd hand clip/hanger function, as further illustratedin the following:

-   -   The retainer means 301 provides attachment features to support        assembly to the base frame 110 as well as the door, by being        formed with the hook 350 and clips 315, 316, 360. Two clips 315        and 316 serve the attachment to the base frame 110 as best seen        in FIGS. 1a, 1b and 5 b. The hook 350 primarily serves to hold        the exterior rear view device 1 in Y direction to assist        assembly of the screws (not shown), while the third clip 360 is        on secondary location keyway to highlight when the exterior rear        view device 1 is in its final assembly Z position, as best seen        in FIG. 2 d.

The retainer assembly 300 comprises, in addition to the retainer means301, a sealing means 800 in form of a 2K door gasket. Before describingthe structure and function of the sealing means 301 in detail, in thefollowing further assembly steps via simple clip connections aredescribed with reference to FIGS. 3a to 5 c:

The slim design of the base frame 110 allows a case lower or lower case220 of the head assembly 200 to be assembled over the door attachmentportion 115 and the arm 116 of the base frame 110 to reach the region ofthe head assembly 200, as shown in FIGS. 3a to 3f together with FIGS. 4ato 4f . In this respect it is to be noted that it is critical toassemble high gloss components like the lower case 220 late in theassembly sequence to minimize risk of damage. For that purpose the lowercase 220 is provided with an opening 222, preferably being substantiallycircular, through which the base frame 110 together with the retainermeans 301 can pass.

The sealing means 800 is mounted after the lower case 220, as shown inFIGS. 3f and 3g . The sealing means location strategy is critical as itdictates the datum strategy for the corresponding base cover componentsdiscussed with respect to FIGS. 6a to 6g below.

Thus, the smaller base frame geometry and the provision of a separate 2Kdoor gasket provided by the sealing means 800 permit the lower case 220to be assembled over the base frame 110, and a T section supportstructure for the base cover permits a simple clip together assembly.

In to following the attachment of the sealing means 800 is describedwith reference to FIGS. 5a to 5 c:

-   -   Four clips 810, 820, 830 and 840 allow to attach the sealing        means 800 to the base frame 110, with the base frame 110        comprising complementary steps 135 and 136 as well as openings        137 and 138.    -   The two screw positions determined by the openings 881, 882        allow to secure the sealing means 800 and retainer means 301 to        the base frame 110. These are package protections only if more        strength is required.    -   A datum area 850 for a base cover and a T-slot built into both        the retainer means 301 and the sealing means 800, see the T        shaped location projection 390 and the T-slots 391, 851 serve to        maximize and gain strength from the base frame 110 into the area        for base cover assembly.

The sub-assembly of the base frame 110, the retainer means 301 and thesealing means 800 forms a channel 900, see FIGS. 6a and 6b , forpositioning/locating a glass run seal 920 in particular allocated to acheater panel 640 as shown e.g. in FIG. 6c . In the following theattachment of a base cover cap 150 and a base cover upper or upper basecover 180 are described with reference to FIGS. 6c to 6 f:

-   -   The combination the base frame 110, the retainer means 301 and        the sealing means 800 forms the channel 900 which locates the        glass run seal 920 on to the exterior rear view device 1. The        glass run seal 920 runs along the cheater panel 640 and is an        extension of the glass run seal running along the window 1000        and being covered by a door trim 940 as shown in FIGS. 6d and 7.    -   The base cover cap 180 clips to the base frame 110, see FIG. 6d        , and also the upper base cover 190 is attached by clip        connection, see FIG. 6e . The clip connection may be located        behind a chrome wait finisher (not shown).    -   The cheater panel 640 pushes the glass run seal 920 into the        correct position inside the channel 900 while being assembled.        The base cover cap 180 and the upper base cover 190 assemble in        such a way that when rotating into their position a sealing lip        of the glass run seal 920 is pushed against the cheater panel        640 sealing the gap between the base cover cap 180 and the upper        base cover 190 on the one side and the cheater panel 640 on the        other side, see FIG. 6 f.

Thus, the exterior rear view device 1 holds the glass run seal 920 in asolid position as shown in FIG. 6f . This provides a very pleasingoverall appearance suggesting that the exterior rear view device 1extends or rather grows out of a wait finisher 940 covering a part ofthe glass run seal 920, see FIG. 7.

It will be appreciated by those skilled in the art that changes could bemade to the embodiments described above without departing from the broadinventive concept thereof. It is understood, therefore, that theinvention disclosed herein is not limited to the particular embodimentsdisclosed, and is intended to cover modifications within the spirit andscope of the present invention.
